Lacing e-cigarette liquid with sucralose is probably not a sweet idea. Vaping the synthetic sweetener may generate harmful chemicals, researchers report May 13 in Chemical Research in Toxicology.
“I would strongly advise that users should not use liquids with sucralose in them,” says Sven Jordt, a toxicologist at Duke University School of Medicine who was not involved with the study.
Many e-cigarette users, especially teenagers (SN: 12/22/18, p. 28), are drawn to sweet and fruity flavored e-liquids. But because of lax labeling rules, it’s not clear which e-cigarettes include sucralose and how much they contain. The popular Juul brand does not contain sucralose, Jordt says. Manufacturers also sell concentrated sucralose solutions for users who mix their own e-juice.
